ELECTRIC HEAT

Units with electric heat are fully wired and operational when
shipped. Constant volume units are designed for two equal
steps of capacity for 80 and 108 kWH heat; 40 kW heat is one
step only. VAV units are one full step at full heat capacity.

HOT WATER HEAT

The YORK Millennium units (25, 30, and 40 Ton sizes) can be
furnished with a YORK hot water coil as the heat source. One
or two row coil units will be factory installed in the heating
section.
NOTE: The hot water control valve will not be provided. The
installer will need to purchase a hot water control
valve, to connect the hot water piping and power
wiring at the job site for the hot water heat section to
be operational.
